Action Boost 3 Lucky Rainbows Slot – Free Demo

The pots above the reels

SpinPlay Games has built Action Boost 3 Lucky Rainbows around a device that pins the entire game on coins tumbling into pots. Each Coin that lands collects to the pot of its own colour, and there are three of those sitting above the reels in the base game. Let me put Action Boost 3 Lucky Rainbows through its tests.

Action Boost 3 Lucky Rainbows is a green slot situated somewhere over the rainbow. A jackpot panel sits top-left with Mega, Major, Minor and Mini stacked in it, reading 60,000.00, 6,000.00, 600.00 and 120.00 at the 12.00 bet I played. It is brimming with gold and shamrocks. Those four figures hold still in the base game; inside the Red Coin round a jackpot boost raises one of them for the remainder of the round. The Irish theme is emphasised by the three rainbows curving above the grid, the reels are packed with equally green symbols, and the pots sit above them.

Where the Wild does its second job

Players receive some pleasingly hefty symbols on the game's 5x4 grid. In the Green Coin round every reel grows to a height of six positions. The wild is stacked on all reels. Five Wilds on a line is the top line pay at ten times the stake, which at the 12.00 bet is 120.00 — the same figure as the Mini. There are Bonus symbols in the form of coins - green, red, purple and the Pot of Gold - and those are the ones that start everything.

Payouts happen when matching symbols land from the leftmost reel on neighbouring reels along a payline, and the wild symbol assists in this respect by standing in for any of the pay symbols. The Green Coin round goes further with it: any reel showing a Wild is nudged until every position on that reel is Wild, and wins are paid after the nudge. Bear in mind it does not stand in for the Bonus symbols. That same round can also upgrade a symbol to the Clover, and the upgrade resolves before any wins are paid. The game operates 20 paylines as standard, and 40 when the Green Coin features are active, which is the only time the line count changes.

A Pot of Gold Coin and one Rainbow Spin

Let me commence with a summary of the Rainbow Spin. Every Pot of Gold Coin collects to the Pot of Gold whether or not the spin comes with it. It can be triggered whenever a Pot of Gold Coin lands, and when it does, one Rainbow Spin is awarded with all rainbows active. Coins landing on the rainbows trigger the Action Boost Free Spins, the combination determines which one is awarded, and the Rainbow Spin can also merely award Mega, Major, Minor or Mini.

Four Action Boosts from the same pots

Lastly, the concluding feature is the Action Boost Free Spins game, and coins collecting to the pots trigger it. The combination of Coins sitting in the pots at the moment it triggers is what decides which Action Boost you are handed. The bet multiplier is the one from the triggering spin. The Action Boost awarded also sets which rainbows are active for any Rainbow Spin that turns up inside the round. Green Coin awards 5 free spins on 40 lines with the reels enlarged to 6 positions, Wild reels nudged to full Wild, and symbols capable of upgrading to the Clover, while Red Coin awards 10 free spins where shamrock collections pay Mini, Minor, Major and Mega. The Red Coin round keeps that tally in the jackpot panel itself, which grows a row of pips beside each jackpot name — three green for Mini, four blue for Minor, five purple for Major, six red for Mega — and fills them as Gold Coins hand shamrocks over, with a completed set paying the jackpot and resetting those pips. Purple Coin awards 5 free spins with a random multiplier of 2, 3 or 5 on every spin. A counter down the right-hand side of the screen tracks progress through the round, reading Free Spin 9 of 10 in the Red Coin round I captured. It can be prolonged by 1, 2 or 3 spins at a time. A rainbow column runs down the left of the screen during a round, stepping coins past credit values and past Mini Boost, Minor Boost, Major Boost and Mega Boost positions. If more than one Action Boost emerges out of the same base spin they are run together, for 10 free spins if Red is among them and 5 if not.

A coin-collection game with extras bolted on

Action Boost 3 Lucky Rainbows is a respectable game. The whole thing hinges on Coins reaching the pots, and nothing else in the base game opens a feature. But let's be frank, the coin-collection element is potent with this one, and SpinPlay Games might have dressed it up by appending four distinct Action Boost versions and four jackpots, but it's essentially a hold-the-coins feature with a few supplementary pieces. SpinPlay Games ships the same device under two other names, 3 Lucky Rainbows Action Boost Max and 3 Lucky Rainbows Action Boost SpinUP.

400 spins at 12.00, one Action Boost

Base game wins keep matters trundling along. Over my 400 spins the balance went from 100,000.00 to 98,206.00, with the high point at 100,319.20 on spin 102. The peak is the Action Boost round which can total up handsomely, and when stretched to its limit, Action Boost 3 Lucky Rainbows caps out at 5,000 times the stake. The Mega on the panel read 60,000.00 at the 12.00 bet, which is that same ceiling in a single award. My own 400 spins at 12.00 got nowhere close to it: 100 paying spins, 45 of them beneath the stake, a solitary Action Boost round on spin 96 that paid 912.00, or 76 times the stake, and a conclusion at 62.6% of everything wagered, and there was also an 18-spin span with nothing whatsoever.

Minty’s Final Note: One Action Boost round in 400 spins carried 30% of everything the session won, and the other 70% arrived across 100 paying spins, 45 of which came in under the stake. The four rounds are built differently enough to be worth telling apart before one arrives, and the coins already sitting in the pots decide which of them it will be.

What the base game paid behind it

At the end of the day, as a freestanding slot, Action Boost 3 Lucky Rainbows is fairly good, and the four rounds are genuinely different from each other. That one round ran its 10 free spins without retriggering and accounted for 30% of everything I won. Potential is there owing to the jackpots and the four Action Boost rounds. The next two best spins were base game wins of 312.00 on spin 239 and 228.00 on spin 329. And yet. Watch this space.
